AGF700-48S30LT中文资料700 Watt Isolated DC-DC Converters for RF Applications数据手册Artesyn规格书

描述 Description

The AGF700 series isolated DC-DC converter is designed for the type of RF power amplifiers used in micro and macro cell, NodeB/eNodeB and remote radio head (RRH) telecommunications applications.The converter accepts a wide range input of 36 to 75 Vdc and provides a low noise regulated 28 Vdc output that is capable of delivering up to 25 amps. The output can be trimmed from 15 to 33 V to address a broad range of application needs. Rated at 700 watts, the converter can operate over an ambient temperature range of -40 to 85˚C, continuing to deliver full power up to a baseplate temperature of 100˚C. It uses 320 kHz fixed-frequency switching to help minimize external EMI filtering requirements.Employing an aluminum baseplate structure, AGF700 series converters have an industry-standard full-brick footprint and pin-out, with an installed height of just 0.5 inch (12.7 mm). They provide an ultra high conversion efficiency of 94.5%. Standard features include differential remote sense, remote ‘power good’ indication and remote enable, as well comprehensive protection against input undervoltage, overtemperature, and output overcurrent or overvoltage conditions. The converters support current sharing for parallel operation.
